nRF9160 - Secure boot implementationhttps://devzone.nordicsemi.com/f/nordic-q-a/124255/nrf9160---secure-boot-implementationHi Team, We have started our cellular development using nRF9160 modem using SDK 3.1.0. We have selected this MCU because it support all security features, we are going to start secure boot implementation. Can you please provide detailed stepsen-USTelligent Community 13Tue, 09 Sep 2025 15:09:52 GMTRE: nRF9160 - Secure boot implementationhttps://devzone.nordicsemi.com/thread/548268?ContentTypeID=1Tue, 09 Sep 2025 15:09:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a615b2f7-6dd4-4104-8417-d7e6bedabe40dejans<p>Hi,<br /><br />Is there any specific reason for choosing nrf9160? For new design projects we recommend using nrf9151. You can find this recommendation on&nbsp;<a href="https://www.nordicsemi.com/Products/nRF9160">nrf9160</a>&nbsp;product page. Both nrf9160 and nrf9151 have support for Secure Boot.<br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1757429621064v1.png" alt=" " /><br /><br />Regarding samples, there are&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bootloader/README.html">nRF Secure Immutable Bootloader</a>&nbsp;and&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/zephyr/smp_svr_mini_boot/README.html">MCUboot minimal configuration</a>.&nbsp;<br />We also have comprehensive documentation related to Secure Boot:<br />-&nbsp;<a href="https://docs.nordicsemi.com/bundle/nwp_057/page/WP/nwp_057/security_services/secure_boot.html">Secure Boot</a><br />-&nbsp;<a href="https://docs.nordicsemi.com/bundle/nwp_057/page/WP/nwp_057/from_silicon_to_cloud/secure_boot_and_update.html">Secure Boot and Secure Update</a><br />-&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_sysbuild.html#secure_boot">Migrating to Sysbuild - Secure Boot</a><br /><br />Best regards,<br />Dejan<br /><br /><br /></p><div style="clear:both;"></div>
